Suella Braverman, the UK Home Secretary, told the Times UK that the government was considering tightening the rules on dependant.

The Home Office immigration figures revealed inconsistency across different nationalities coming to the UK to work and study.

According to a Home Office report, Nigerians accounted for 40% of all dependants who accompanied foreign students in the 12 months to June 2022, despite Nigerian students constituting only 7% of all foreign students during that time period.

34,000 Nigerians were given study visas in the UK, bringing with them a total of 31,898 dependants. A similar ratio was recorded for work visas, with 8,972 Nigerians issued with one in the 12 months to June bringing with them 8,576 dependants.

By comparison, the figures show that 93,049 Indian students who came to the UK last year brought with them 24,916 dependants, while 114,837 Chinese students came to Britain with 401 dependants.

It said: “There were 117,965 grants to Indian nationals in the year ending June 2022, an increase of 80,569 (+215%) compared to 2019. Chinese nationals were the second most common nationality granted Sponsored study visas in the year ending June 2022, with 115,056 visas granted, 4% lower than the number seen in 2019 (119,825).”

“In the other top 5 nationalities, Nigerian nationals saw the largest relative increase in Sponsored Study grants compared with 2019, increasing by 57,545 (+686%) to a record high of 65,929, making them the third largest nationality group in the latest year,” Home office said.

A Home Office official told Daily Mail: “This is the highest on record in our time series, with the substantial increase representing both a recovery from lower numbers during the Covid-19 pandemic but also an increase on the pre-pandemic period.”
